It seems like online stores are just as if not more expensive than sportsmans warehouse, but I've had trouble with sportsmans not having anything in stock.[\quote]
There's an old joke. A women goes into a butcher shop and says how much do you charge for ground beef. Butcher say, $1.25/lb. Lady tells him the butcher across the street has ground beef for eight-nine cents a pound. Butcher says to go across the street then. Lady says the shop across the street is out. Butcher tells her he could sell them all day long for eight-nine cents a pound if he were out too.
But I...er....digress. To answer your question. My favorite bullet dealer for bulk handgun bullets is Magnus Bullets. They can ship up to 70# for only $12 via USPS Flat Rate. Makes them very competitive. They have both cast and jacketed.
